18 Claims. (Cl. -13) This invention relates in general to a convertible seat of the folding chair or davenport type and is more particularly described as an improved folding seat mechanism in which the seat section is inverted rearwardly in changing it from a seat to a bed form. t

An important object of the invention is to provide a convertible seat bed having an improved seat folding mechanism by which the seat section is inverted rearwardly and the other bed sections are moved upwardly and outwardly over a fixed front rail with the movements of all of the seat sections coordinated by the folding mechanism as the construction is changed from a seat to a bed and is returned from extended bed position to form a seat.

Other objects of the invention are to provide a convertible seat structure which provides for a fixed front rail connecting the ends of the seat frame within and over which some of the folding sections are movable in order to change it from one limiting position to the other; to provide positive coordination of the overturning of the seat with the controlled unfolding of the other bed sections; to provide for easier operation of the folding structure at the start of the closing operations; to provide a unitary folding construction which is adapted to be applied to and removed from a chair or davenport frame for easily setting up a complete article of furniture and for partially dismembering it for shipment and storage; to provide improved counterbalancing and unfolding movements of the sections which are supported in an intermediate position by one of the legs in the folding and unfolding movement; to provide a convertible seat structure with a fixed front rail, of full height and coordinated folding sections to move automatically over the rail, which contribute to the practice of good and improved design and freedom in styling of furnitureof this type; and in general, to produce the structure herein shown and described.

Other objects will appear hereinafter, the preferred embodiment of the invention being illustrated in the accompanying drawings in which,

approximately on the line tremity 29 of this mounting bar extends a short distance 2,724,126 Patented Nov. 22, 1955 In convertible furniture of the overturning seat type, it has heretofore been difficult to provide a sutficiently rigid connection for the frame ends of the supporting arms and at the same time to provide a fixed front board of sufficient height at the front of the frame so that a pleasingly upholstered article of furniture may be produced. 1

In the present invention, a relatively high front board is fixed in position and the folding structure is first raised from below the seat to clear the top of the front board and to unfold outwardly and downwardly in a controlled movement without requiring a heavy lifting operation at any stage of the folding or unfolding movement.

Referring now more particularly to the drawings, this invention comprises a mounting frame which may be in the form of a chair or a davenport having side frames or ends 10 connected by a back 11 and the fronts of the ends connected by a front board 12. No special provision is made for covering or upholstering this frame but it is usual to provide a back cushion 13 which has a lower fixed rail 14 below and partially behind which some of the mechanism swings in changing the construction from a seat to a bed. The invention comprises particularly the metal folding sections which are mounted at the inside of the frame ends 10 and are adapted to.

15, an intermediate section 16and an outer section 17.

These sections are usually composed of metal angle bars within which are connected wire fabric constructions 18 in the front and intermediate sections and fiat metal strips 19 in the seat section. These fabrics are drawn tightly in each section by helical springs 20 and extend throughout each section, together forming a bed bottom when the sections are extended for supporting a mattress and bed clothes. provides a surface upon which a seat cushion maybe secured or loose cushions may be freely deposited in a well known manner.

In changing the folding construction from a seat to a bed, the seat section which is uppermost, as shown in Fig. l, is overturned rearwardly within the frame and the intermediate and outer folding sections are swung upwardly over the fixed front rail while the seat section is being overturned within the frame and then the intermediate and outer sections are moved outwardly and downwardly into alignment with each other and with the seat section overturned within the frame as shown in Figs. 4 and 5.

The seat section comprises angle bars 21 at each end connected by a cross bar 22 which is at the front of the frame in uppermost position as shown in Fig. l, and near each end or at the middle of the cross bar is a pivoted latch 23 adapted to engage in a notch 24 near the upper edge of the inside of the front board 12.

At each end of the seat section is a spacing plate 25, preferably a short piece of angle bar which has one web attached by rivets or fastening bolts 26 to one web of the angle bar 21 and another web parallel to the.

other web of the angle bar but spaced therefrom as clearly shown in Figs. 5 and 6 which provides a support for an irregular fixed mounting bar 27 secured to the other web of the spacing plate by rivets 28. One exfrom the end bar 21 and the other extremity 30 extends further away from the bar 21. pivoted one end of a link 31 which is in the shape of a The seat section in particular To the extremity 29 is i a pivot 32 with a mounting strap 33 which is adapted to be secured to the inside of the adjacent frame end by fastening screws 34. To the other end of the mounting strap, one end of a lever comprising an arm 35 is connected by a pivot 36 and the other end of this arm has a plate 37 rigidly attached thereto with an offset 38 adjacent .its connection-with the arm. The other end of this plate 37 is connected by a pivot 39 with the extending end of the irregular mounting bar 27. Thus the seat section is pivotally mounted for overturning movement within the seatframe by these two members, the link 31 and the lever .35, 37 which are connected to opposite ends of the irregular mounting bar 27-. The. ends. of the mounting strap 33' are preferably offset outwardly as shown more :clearlyin Fig. 5 so that the pivots 32 and 36 of. the mounting links will not engage the ends and the members 31 and will be spaced inwardly and from each other and so that thebell crank link 31 will be seated in the space provided by the spacing plate 25 when the'seat section is at rest in the seat position as shown in Fig. l.

At this time, the seat section is supported by an angle bracket 40 (at each end) secured to the end frame 10 by fastening screws 41 and projecting inwardly therefrom below the mounting strap 33. It is in this position that the pivoted latch 23 '(or latches) at theadjacent side of the seat section is turned into engagement with the notch 24 at the upper edge of the front board;

In order to cushion and assist the overturning movementsof the seat section, a coil spring 42 :is connected atone .end to a point 43 substantially in the angle of the bell crank .link 31 and it is connected at its other end to a projection 44 from the end of the arm 35 adjacent but .at-one side of its pivot 36 by which it is connected to the strap 33. The pull of thisspring-tends to raise the seat section in the frame.

Extending upwardly from the seat section in its seat v position .is. a strengthening yoke 45 which has a fastening 46 at each/end connected with one of the side rails 21 andjoiningand strengthening it at this side which is opposite the fixed rail 22 at the other side-of the section. This yoke is strengthened and positioned at each end by a link 47 connected at oneend to the inside of the adjacent angle bar 21 and connected by a fastening 43 at the other end with the adjacent side of the yoke 45 intermediate the upper and lower portions of this side so that the yoke is held firmly in itsextended position. The cross piece of the yoke-45 is thus spaced materially below the mattress supporting fabric (-18, 19) of the bed so that it will not be engaged even though the weight of a person upon the bed is :suflicient to depress the mattress and the wire '49 preferably formed integrally by bending it therefrom,

and this abutment engages the bent extremity 30 of the irregular mounting bar 27 in one direction of movement to limit the movement of the seat section the bed 7 forming position as shown in Fig. 4.

Between the intermediate section 16 and, the seat sec tion 15, there is a double connection at both ends of the sections. One. connection consists of a link 50 connected at one end'by a pivot 51 to the adjacent, side of the yoke 45 near the outermost portion thereof, and the otherlend isconnected by a pivot 52 with a .side bar 53 of theintermediate section 16. The otherkcon nectioninclucles .a coordinating lever .54 having, a bent extremity .55 and. connected by a pivot 5.6 adjacent the angle of the bent extremity 55 to the. end of the adjacent. angle. bar 21.. The end .of this bent extremity '55 is connected .bya pivot 57 with one end of a short link'58,

the other end of which is connected by a pivot 59 with the free end of the plate 37 which is attached to the link 35. This link 58 has a limited movement on the plate in one direction and a stop 60 is positioned thereon to engage the link when it is moved in that direction. This likewise limits the movement of the lever 54 when it is swung about its pivot 56.

'The connection of the seat mounting parts with the link 50 and the coordinating lever .54 by means of the short link 58 automatically controls the overturning movement of the seat in changing it from a seat to a bed construction (and from a bed to a seat) and also coordinates v the action of the seat with the folding movement of the other sections.

The other end of each coordinating lever 54 has a bent extremity 61 connected by, a pivot 62 near one end thereof at one side of a plate 63 secured to one end of the angle bar 53 at each end of the section 16. The end of the extremity 61 is connected by a pivot 64 with a leg ,folding lever 65. The other end of this lever 65 is connected by a pivot 66 with a hinge plate 6.7 secured to a side angle bar 68 of the outer bed section 1.7. The side bar 53 of the intermediate. section is connected to this same plate A 67 by a pivot 69 so that these two side bars 53 and 68 will rotate about each other from a right angle position as .shown in Fig. l to a position in alignment with each other as shown in Figs. 4 and 5. The lever 65 also coordinates thefolding of sections 16 and 17.

A leg 70 is pivoted to each plate 63 at the side opposite the connection of the lever54 by a pivot 71 and the two legs at opposite sides of the sections are joined by an angle bar cross. base 72. Near its pivotal mounting, a plate 73 is secured to each leg which has a pivot 74 engaging oneend of a link 75, the other end of the link being connected by a pivot 76 with the coordinating lever 65 adjacent its pivotal connection with the coordinating lever 54. The unfolding movement of the sections 16 and 17 from a position as shown approximately in Fig. 2

to that shown in Fig. 3, causes a quick unfolding movement of the intermediate supporting legs 70 before the bed sections reach their position of alignment which helps to support them for their final or aligning movement.

To assist the folding movement of these legs 70, a coil spring 77 is connected atone end to the cross bar 72 adjacent each leg and the other end of each spring is connected to the bar 53 slightly inwardly from the pivot 71 of the leg itself so that in the folding movement of the construction when the outer end is raised, the springs 77 will assist the inward folding movement of the legs 70 when the. outermost section 17 is raised.

A pair of legs 78 are pivoted to the opposite side bars 68 of the .outer section 17, one at each side. thereof, by means of a .pivot 79 intermediate the ends ,of the side bar 68, the legs being joined by a cross bar 8.0 intermediate the top and bottomthereof. To automatically fold these legs 78, a link 81 has a pivot 82 atone end connected near the upper end of one of thelegs 7$ and the other end of the link has a pivot 83 conneetingit to the leg foldinglever 65 adjacent to its pivot 6 6. :The outer ends of theside bars 68 are connected by a cross bar 84 which is continuous therewith or firmly secured thereto to provide with the cross bar suflicientlstrength and resistance to a collapsing movement of the bed sections due to a weight or load thereon.

When the mechanism is folded within the seatframe, the sections 16 and 17 with their connections are swung below the seat sectionjandrat the rear of the frame.;partially behind the seat section and below the ,back cushion in.this position, the. seat section is partially supported at each end byan angle, bracket40 projecting inwardly from the frame end. At the front of the seatsectiqll. in .the seat positionlis another support 85 securedtoeach frame end having an upper projection 86-which engages -the adjacent side bar "21 of the seat section and a'lowerinner projection 87 which may extend further inwardly to engage the outer edge of the outer section 17 in its folding position as shown more clearly in Fig. 1.

' carrying the seat sections 16 and 17 therewith and assisted by the springs 42. Since the bed sections areall mounted ,toswing in the frame upon the members 31 and 35 and the sections 16 and 17 are held in right angled position and are suspended by the links 50 and 58 and coordinating levers 54 at each end of the sections, the upward movement of the seat section swings the other two sections upwardly and forwardly free from engagement with the upper edge of the fixed front board 12 in a path substantially as shown by Fig. 2 atwhich time the coordinating linkage comprising the lever 54, and the short link 58 have guided the overturning movement of the seat section because of the connection of the lever with one end of the side bar 21 and because of the swinging movement of the seat section upon the links 31 and 35 as guided by the short link 58 connected to the plate 37 and as directed by a swinging movement of the coordinating lever 54 attached thereto.

This preliminary movement of the seat, intermediate and outer sections together for the first portion of the swinging movement of the sections does not materially affect the relation of the sections 16 and 17 until after they pass upwardly and outwardly over the top of the front board to the position as shown in Fig. 2. At this time they are movable relatively away from the section 15 and the connecting links 50 and levers 54 are automatically effective first to swing the sections 16 and 17 outwardly and downwardly until the legs 70 engage the supporting surface for the article of furniture at which time the seat section is completing its overturning movement as shown in Fig. 3 and all of the sections are substantially supported by the inner legs 70 as the outer section 17 continues its downward movement as controlled by the coordinating linkage, which conducts the seat sections and the other sections.

In the folding movement of the sections to form a seat, the unfolding action is reversed. The operator raises upwardly at the outer side of the outer section 17 which raises the legs 78 and commences to fold them when the outer section is in a partially raised position as shown in Fig. 3 at which time the coordinating linkagehas also partially raised the seat section to the position therein shown and the continued upward raising movement of the outer seat section then folds the legs 78, raises and folds the legs 70 and swings the adjacent connected end of the seat section downwardly to a position as shown in Fig. 2. Continued inward movement moves the sections 16 and 17 to a right angled position at the end of the seat section and all of the sections are then swung upon the members 31 and 35 inwardly below, the seat section.

, The intermediate and outer sections are supported in this mounting links 31 and 35 and also by the coordinating linkage which extends firmly between the intermediate section and the seat section since both the link and the lever are firmly pivoted to the seat section and the intermediate section. Thus the operation of the coordinating linkage comprising the links 50, the levers 54 and the short connecting links 58 control the folding movement of all of the sections from the start to the finish in either direction, the manual engagement thereof being only for the purpose of furnishing the motive power.

While a preferred embodiment of this invention has been described in some detail, it should be regarded by way of illustration and example rather than a restriction or limitation thereof, as many changes in the construction, combination and arrangement of the parts may be made without departing from the spirit and scope of the invention.
